Sleeves l6arethreaded' onto the lower and projecting ends of the clampingposts 14and form legs for the front end otthe casting machine. i 1 i i.Hinge'brackets '17' are securedto thefrea r' I Fourth :to provide acasting machine comond of the: bottomiplate ,bymeans of the V prisingtransversely and longitudinally ex screws 18, or in any ether suitablemanner, and each comprlsesthe two spaced bifurcatrons 19' between WlHClLJS recelved the eye receivingt-he hinge posts 21. Preferably,

theseiposts are provided with the, annular shoulders 25; againstwhichthe eyes24rest. The vplate 23' is rigidly held in place upon the hingeposts by means-,of'the thumb screws 26, which engage theouter threadedendsot the hinge. posts, and means ofthespacing sleeves 27, the detailedconstruction and" function of whi'ch will be described laterfon.

A lug 28 -projectingiupwardlyiromjthe rear end of the top plate23provides a support for the rearfw'ardly extending 1eg29.

This leg,,-in combinationwith the leg lf z, provides means forsupporting thefcasting ;ma ehine ,in' '21} vertical position, as will bereferred tojin thedescription of the oper-' ation of my machine; Inthe'raised position of the top Pla es (shown inv Fig. 2);,gthef-leg 29restszag'ainst the lug 29 1projectingreariwardlycfr'o m the bottomplateh j 'Rotatably mounted 'upon the clamping posts 14, are sleeves'BOeach having an annularjshoulder or lug 31ye itenfdingirom the I bottomthereof and'a second lug' BQfpr ject I ing from the upp er end thereof.The lug 32 does not extend entirely around the sleeve 3'0. WVith theselugs turned to the position shown in Figure 3, the bottom of the topplate rests upon the lug or shoulder 31, the thickness ofthis elementbeing such as properly to space the top plate from the bottom plate forcasting plate high plates. When, however, the sleeves are rotatedtoposition the lugs 32 beneath the top plate, as

' will be described later on, the two plates second sleeve 33, whichcarries a clamping bracket 34, the outer end of which is provided withan internally threaded boss 35 for receiving the threaded clamping screw36, the lower end of which is adapted to engagethe top side of the topplate. r

The upper ends of the clamping posts 14 are threaded for receiving thumbnuts 37' and between the latter elements and the sleeves 33 areinterposed spacing sleeves 38,-

to bereferred to later on. V

Brackets 40, secured to and extending upwardly from the top plate,provide means for securing the handle 4:1 to the top plate. .A rail42extends transversely of and is secured to the front end of the bottomplate by means of the posts l3, which project outwardly from the frontend of the. bottom plate. This rail acts as a support for the V slidingshoes er,- which are yieldingly held in any of their adjusted positionsupon the I rail 42 by means of the bow springs 45 in terposed betweenthe bottom of the rail and the bottom of the shoe. 7 The upper sides ofthe shoes are provided wlth'transversely extending rectangular grooves46for receiving the gauge .barsili'. Thes'e bars are yieldingly held intheir adjusted positions by means of the clamping plates l8 which arepivoted to brackets 49. "extending upwardly from the shoes, by meanslofpins 5O, and yieldingly held in engagement with the gauge bars means ofthe springs 51, which are coiled I about the pins 50. Theouter ends ofthese springs engage the lower side of the outer ends of the clampingplates 48 and yieldingly urge them upwards. By means of the constructionjustdescribed it will be apparent that the gauge bars 47 can beeasilyfand quicklyadjusted both longitudinally :and transversely of themachine.

5 For co-acting with the inner ends of the gauge bars 47, I provide thetransversely extending gauge bar 52, each end of which is provided witha shoe 53 which slidingly engages the adjacent edge of the bottom plate10. One of-the shoes is provided with the thiimb niece 54 and the othershoe has a downwardly extending lug 55 (see Figure 5) in which ismounted the set. screw 56, one

top plate is also provided with longitudi end of which is adapted to bebrought into engagement with the flange 57 extending downwardly fromthebottom plate to lock the gauge bar 52 in any of its adjustedpositions. The headof the screw 56 may be, 7

used for the same purpose as the lug 54, for adjusting the bar 52longitudinally of the castin g machine.

By reference to Figure 6, it will be noted that for casting plate-highplates I provide longitudinal gauge bars 47, one face of which is outaway'or' beveled ad acent one edge thereof, as shown at 47 in Figure 6'for receiving between it and the bottom plate one edge of the mat 58.The opposite 7 face of the gauge bar is also cut away, as shown at 47.for the purpose of casting a alate havin deoressed mar ins throu h- :s..t b

shownat 52 in Figure 5 for receiving the edge or margin ofitlie mat.

Some mats are provided with paper extensions (or aprons) which extendoutwardly beyond the front ends of the top and bottom platesto preventmetal from running down between the mat'and the bottom plate, and topermit these aprons to lie flat along the front edge of the bottomplate, I notch the shoes 44. assho'wn at 59 (see Figure 3) to 1 receivethe edges of the aprons.

T have already referred to the flange 57 extending downwardly from the:bottom plate 10. This flange extends "entirely around the bottom plateand a similar flange 6O extends-upwardly from the top plate. The

nally and transversely extending intersectingribs 61 and '62,respectively, The bottom plateis provided with similar ribs which arenot shown. One of the functions of these ribs and the flanges 60 is tomake it possible to reduce the thickness of the I top and bottom plates,but at the same time to hold them rigidly against any, tendency to warpor bend under the influence of :the

heat-and pressure towhich they are subjected during use. a p

"When 'my improved casting machine is used for casting plate-highplates,'the spacing sleeves 27 and 38 are respectively positioned asshown in Figures when it is used for'ca'sting type-high platesthesleeves 33, carrying the clamping bracle ets 34,are reversed, as shownin Figure 8, and the spacing sleeves 27 are placed be- 2, 3'and l, but2f .the positions of the spacing sleeves scene tween theeyes 24c'and theannular shoulders 25. ,The thumb screws 26 willthen bear directlyupon'the upper sides of the eyes 24.

In casting type-high'plates a suitable typehiglr gauge barl'? (seeFig.8) is used for spaclng the top 'and'bottom plates;

For the purpose of'facilitating the ad-' justmentofithe top platerelatively to the:

bottom plate, I provide-the spacing sleeves 27 and-38 withlongitudinallyextending slots .63, which permit the removal of the sleeves 1 from theposts 14 and2l' by alateral move Inent. For yieldingly holding thesleevesv upon these posts'l: provide the'ring-shaped spring 64,Wl'1iChIls positioned in the c'ounter-sunk bore 65 in one end ofthe/sleeve and is. securedin-plac'e by means of a rivet 66, or inanyother suitable manner. The ends of this spring arecurve-d outwardly, asshown at 67,.to' engage the sides of the posts to spring these endsoutwardly when i the collar is to be replaced upon one of the posts;

the gauge bars. The, casting machine is then raised-to a verticalposition and stood upon the legs 12 and 29, whereupon molten metal canbe poured between "the; upper ends ofthe two'plates,-the end of thetopgplate' preferably beingTbeveled, as shown at 68,

to facilitate thisoperation. ;l/Vhen the metal has solidified, theclamping screws 3.5 can bis released, the upper plate: turned back andthe plate remove I Whilemy improved machine can be made of cast iron, orany other similanmatrialf I'prefer to'makeit outofmaterials having highspecific heats andheatconductivities, as Izhave discovered that by theuse of such metals, it is not onlypossible to quickly bring the castingplates to theproper initial H temperature, but that they will remain hotH enough over considerable periods of time to enable successive casts tobe made without the necessity of again preheating them, and

I can obtain these results with casting plates I containing veryconsiderably 'lessl'i'netal by volume than has heretofore been foundnecessary. To'obtain these results, I" have found that aluminum and itsalloys, particularly. its: copper alloys, are; very satis factory. Asmuch as,10%gor: 15% of copper'has been found toiprovide a satisfactoryalloy, although it is to be understood that considerable variations fromI these percentages may beimade without departing from myinvention. V l--Not only does the use of the v,Inaterial specified. above expedite themaking of" plates by cutting down the time initially ing it possibletohave longer intervals of but they also make it possible to morerapidly cast theplates, because I have ifound that theywill abstract theheat from. the molten metal muchmore rapidly than cast iron.-

To requirediforheating the plates and by maktime between the casting ofsuccessive plates,
